how to send styles with html email - php

Question

I am using PHP mail() function to send the email. I have a table in the email with specific styles, but when I receeve the email, it does not show me the images and all style is disturbed.
My code is below:
$recipient = $_POST['Users']['email'];
$name = $_POST['Users']['first_name'];
$username = $_POST['Users']['username'];
$password = $_SESSION['password'];
$referrer_name = $model->referrer = $referrer_data['first_name'];
$referrer_email = $model->referrer = $referrer_data['email'];
// print_r($referrer_name);
// print_r($referrer_email);
$webstore = $this->base_url . "/" . Yii::app()->session['username'];
$headers = 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
$subject = "Sign Up- Success";
$message = "<table width='700' border='0' align='center' cellpadding='0' cellspacing='0' class='bordermain'>

<td align='center' valign='middle'> </td>

Answer 1

You can put your styles inline in your elements
<p style="color:#000">...</p>
And you should use the PHP header
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
$headers .= "MIME-Version: 1.0\r\n";

Answer 2

The reason you cannot use css other than inline and you are best advised to use table based layouts is that some if not most of the email clients such as outlook for example have VERY VERY old version of the browser embeded in them to show an html email.
So unfortunately all email has to be created like we were back in the days of IE6 or before.
As to your images not showing that is because you have to remember when the email is being read it is not a page on your website, so any images must have a fully defined domain and path like src="http://www.yoursite.net/images/facebook.jpg
